摘要
在前期开展的日用陶瓷制品多次4％乙酸迁移试验对铅迁移量的影响基础上,继续开展对镉迁移量的影响研究.试验以日常委托检测样品为对象,研究了连续三次迁移试验和间歇性多次迁移试验及长期迁移试验对镉迁移量的影响.试验结果表明:1)日用陶瓷制品镉迁移量在连续三次迁移试验中呈不断降低趋势;2)在间歇性多次迁移试验中间隔期对镉迁移结果有一定的影响,经过间隔期后的迁移量又有所回升;3)样品经历长期迁移试验后,后期镉析出能力跟样品的初始迁移量水平和制品的表面积S/浸泡液体积v有关.结合前期多次迁移试验对铅迁移量的影响研究结果和GB 31604.1-2015中的规定,日用陶瓷制品铅镉迁移量检测建议可采用一次迁移试验进行.
Abstract
Based on the previous experiments on the influence of multiple 4％acetic acid migration tests on lead migration in domestic ceramic products,this study continues to explore the influence of cadmium migration.The study focused on samples from routine commissioned tests and investigated the effects of three successive migration tests,intermittent multiple migration tests and long-term migration tests on cadmium migration levels.The results showed that:1)the cadmium migration levels in domestic ceramic products show a decreasing trend in three consecutive migration tests;2)intermittent multiple migration tests show that the interval period has a certain impact on cadmium migration,with the amount of cadmium migration rebounding after the interval period;3)after the long-term migration tests,the later cadmium dissolution capacity is related to the initial migration levels of the sample and the surface area S/soaking liquid volume V of the products.Combining with the previous study results on the influence of multiple migration tests on the migration amount of lead and the provisions of GB 31604.1-2015,it is suggested that a single migration test can be used to test the migration amount of lead and cadmium in daily ceramic products.
